For nearly four years, an Oura Ring has been a constant companion on my finger, a silent sentinel tracking my health data. My journey began with the Oura 3, and for the past 17 months, it’s been the Oura Ring 4. The only time it left my hand was a two-week honeymoon, and even then, I felt a pang of guilt for missing out on crucial data.
My decision to upgrade to the Oura 4 wasn’t a whim; my Oura 3 was showing its age. Daily charging became a necessity, and waking up to blank sleep scores was a frustrating norm. The Oura 4 promised significant improvements: superior battery life, a re-engineered sensor array, and a sleeker, all-titanium build. But with an extra $100 price tag, the question lingered: was this a genuine leap forward, or merely a superficial refresh?
Nearly two years and a wealth of data later, I have my answer. My Oura 4 has been with me through a full pregnancy, the intensity of labor and delivery, and the demanding phase of postpartum recovery. This isn’t just a review based on ideal conditions; it’s a testament to how the Oura 4 performs under the most profound life changes. Here’s an honest look at everything I’ve learned, alongside the platform upgrades Oura has quietly rolled out since its 2024 launch, which further bolster the case for this generation.
And for those looking ahead, the Oura 5 has just landed on my doorstep. Expect an update to this piece after a month of rigorous testing.
Oura Ring 4: Key Specifications and My Experience
The Oura Ring 4, priced at $399 (originally $499), brings several notable enhancements to the table.
Size and Fit: A Crucial First Step
Oura’s complimentary sizing kit is indispensable. Don’t skip it. I discovered that sizes aren’t consistent across generations; my Oura 4 in a size 6 felt slightly looser than my Oura 3 of the same size, while a size 5 was too snug. (A note to Oura: half-sizes are a highly requested feature among my team and beyond!)
While Oura traditionally recommends the pointer finger for its larger, more easily readable blood vessels, internal insights reveal that the middle and ring fingers are also perfectly viable options. The difference in accuracy is minimal, offering a welcome flexibility for personal preference – a relief for me, as I prefer the aesthetic of wearing it on my ring finger.
Design Evolution: From Oura 3 to Oura 4
The most significant design shift is the Oura 4’s full titanium construction, both inside and out. My Oura 3 featured a titanium exterior but an epoxy-resin interior. I anticipated a colder, more metallic feel with the new model, but it’s surprisingly comfortable; after a day, its presence is easily forgotten.
The recessed sensors are a game-changer. The Oura 3 had noticeable raised domes (1.3mm), whereas the Oura 4’s sensors are subtly integrated (0.3mm below the surface), resulting in a smooth, seamless interior. This not only enhances comfort and aesthetics but also contributes to more accurate readings.
I opted for gold in both generations. While the Oura 4’s gold tone is subtly different from my aged Oura 3, I attribute this largely to two years of natural wear and tear on the older model. Both rings will inevitably acquire scratches and a duller finish over time, but for me, this patina adds character. If pristine perfection is your priority, a smart ring might not be your ideal accessory.
Why a Smart Ring Over Other Wearables?
I’ve never been a fan of watches or wristbands; the sensation on my wrist is simply not for me. This personal preference made a smart ring the only viable wearable option. And I’m far from alone: the smart-ring market is booming, projected to grow from roughly $417 million in 2025 to a 22.5% CAGR through 2033. While Oura remains the category leader, the influx of competitors is a positive development, quietly spurring Oura to continuously innovate its platform, not just its hardware.
Dramatic Improvements: Data Accuracy and Battery Life
The Oura 4 truly shines in its core functionality. The enhanced sensor array is noticeably more adept at capturing subtle activity. My ultimate litmus test? My Oura 3 frequently misinterpreted hair-washing as a high-intensity interval training (HIIT) workout. The Oura 4, thankfully, has put an end to those erroneous readings, providing a much more accurate reflection of my actual activity levels.
But the most transformative upgrade is undoubtedly the battery life. Where my Oura 3 demanded a daily charge, my Oura 4 now lasts a full week. This single improvement has eliminated a significant point of friction, making consistent data tracking effortless.
Women’s Health Integration: A Personal Journey
My experience with the Oura 4 through pregnancy and postpartum recovery has been invaluable. The insights it provided into my body’s changes during these profound life stages were genuinely useful, offering a level of personal data that traditional fitness trackers often miss. While there was one frustrating caveat (which I’ll delve into in a future update), the overall utility for women’s health tracking is a strong selling point for this device.
